DETAILED DESCRIPTION OF THE INVENTION
A headlamp mounting structure according to an embodiment of the present invention will be described below with reference to the drawings.
A pair of headlamps 3 are provided on the left and right of the front bumper 2 at the front of the automobile 1 in FIG. 1, and the front end of the front hood 4 is arranged in correspondence with the outer peripheral shape (outer contour) of the headlamp 3. A front end portion of the fender panel 5 is formed.
[0011]
FIG. 2 shows a mounting state of the left headlamp 3 of the automobile 1. The configuration on the vehicle body side where the headlamp 3 is disposed will be described. A lamp support 6 that is a housing portion of the housing 7 of the headlamp 3 is provided at the lower inner side of the front end portion of the fender panel 5. A front member 11 is attached between the upper portions. As shown in FIG. 3, on the engine room side of the fender panel 5, a hood frame 13 having a recess 14 in which an edge of the front hood 4 is disposed is provided.
As shown in FIG. 2, the headlamp 3 has a housing 7 portion accommodated in a lamp support 6, and the housing 7 is positioned on the outer periphery of the lens 9 to provide a front outer peripheral edge 8. A front edge portion 10 of the fender panel 5 is formed so as to conform to the shape of the front upper side portion of the housing 7 as a portion.
[0012]
As shown in FIG. 3, the housing 7 is provided with a tongue-shaped attachment piece 12 which is bent in an L shape so that the tip side protrudes toward the rear side of the vehicle body and has flexibility or elasticity.
The mounting piece 12 is provided with a screw insertion hole 17 for fixing the headlamp 3 in the short leg piece 15, and a bolt 18 is fastened to a screw hole (not shown) drilled in the front member 11. As shown in FIG. 4, the long leg piece 16 of the attachment piece 12 has a tip portion bent slightly upward, a protrusion 19 having a rectangular cross section is provided on the lower surface side, and the tip of the protrusion 19 faces downward.
The mounting piece 12 may be integrally formed with the resin housing 7 as long as it has flexibility, and the housing 7 and the mounting piece 12 may be made of different materials. It is formed so that it cannot reach.
[0013]
In the present embodiment, the attachment piece 12 is branched into a bifurcated shape of the short leg piece 15 and the long leg piece 16 so that the screw insertion hole 17 and the protrusion 19 are provided with a certain interval so as to have flexibility. However, the thickness and shape of the mounting piece 12 may be appropriately changed so as to have flexibility.
In the recess 14 of the fender panel 5, a rectangular long hole 20 is formed at a position corresponding to the protrusion 19 of the long leg piece 16 in a state where the headlamp 3 is assembled.
[0014]
The shape of the long hole 20 is such that the longitudinal direction of the vehicle body is short and the movement of the protrusion 19 in the vehicle body direction is restricted, and the vehicle width direction of the long hole 20 is left and right with the protrusion 19 fitted in the long hole 20. It is formed in a length having a surplus width.
As shown in FIG. 2, mounting arms 21 and 22 having screw insertion holes 23 and 24 are provided at the lower part of the headlamp 3, and bolts 18 are attached to the screw insertion holes 23 and 24 provided in the lamp support 6. The headlamp 3 is fixed by fastening.
[0015]
In the present embodiment, in order to assemble the headlamp 3 on the vehicle body side, first, the protrusion 19 provided on the attachment piece 12 is inserted into the long hole 20 formed in the fender panel 5 and positioned. At this time, since the length of the long hole 20 in the front-rear direction of the vehicle body substantially coincides with the protrusion 19, the protrusion 19 is locked to the long hole 20 and the headlamp 3 can be temporarily held. That is, in a state where the headlamp 3 is about to be removed, the mounting piece 12 receives a force that slides forward of the vehicle body, but is locked so that the projection 19 is hooked in the long hole 20. The protrusion 19 may be oriented downward, but the temporary holding force is increased by forming the front corner portion 28 of the vehicle body to have an acute angle as shown in FIG. Further, since the long hole 20 is long in the vehicle width direction, the protrusion 19 can be easily inserted into the long hole.
[0016]
The attachment piece 12 is bifurcated into a short leg piece 15 and a long leg piece 16 so as to be flexible as long as the strength permits, and further between the screw insertion hole 17 and the projection 19. Since the fixed leg is opened, when the short leg piece 15 of the mounting piece 12 is fastened by the bolt 18, the deformation of the short leg piece 15 due to the positional deviation does not reach the long leg piece 16 side. Therefore, positioning is ensured without the protrusion 19 moving. Thus, the positioning of the headlamp 3 in the front-rear direction is performed by restricting the projection 19 in the front-rear direction of the vehicle body, and the positioning in the vehicle width direction is performed by the screw insertion hole 17 and the bolt 18. The positioning of the direction may be regulated by fitting the long leg piece 16 and the concave portion 14 of the fender panel 5.
[0017]
Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications and changes can be made based on the technical idea of the present invention.
